1063. [Invited] Successes & Failures in Design Solutions During the 30 Year Life of ITER (and how we could have improved) (WED-SS-01)

Neil Mitchell

Invited Oral

Over 30 years ITER has been through many design iterations and multiple novel solutions for the magnets have been tried, in some cases being carried through to successful manufacturing and in other cases being abandoned. Now that ITER operation is approaching, the fusion community is considering possible next steps, to a power producing fusion plant. If we consider the long road ITER has...

1065. [Invited] Lessons Learned in the Development of Accelerator Magnets based on Nb3Sn and HTS (WED-SS-02)

Stephen Gourlay (LBNL)

Invited Oral

Superconducting accelerator magnets, due to their high aspect ratio and field configurations, have some unique design and fabrication issues, particularly for higher magnetic field configurations. After more than a half century, the accelerator magnet community is, for the first time, now on the verge of installing magnets based on Nb3Sn in the Large Hadron Collider at CERN. Much experience...

1071. [Invited] Lessons learnt in HL-LHC interaction region superconducting magnets: two case studies (WED-SS-03)

Dr Ezio Todesco (CERN)

17/11/2021, 19:10

Invited Oral

The upgrade of the LHC to increase luminosity (High Luminosity LHC) requires the construction of six different types of accelerator magnets based on LTS technology. Besides the quadrupoles in Nb3Sn, with peak field of 11.5 T, we have two different dipoles in the 4.5-5.6 T range based on Nb-Ti, and three types of correctors. All magnets are characterized by wide apertures (150 mm), posing...

1062. [Invited] Some Lessons Learned During 27 Years Operating Above 27 Tesla. (WED-SS-04)

Mark Bird (FSU)

17/11/2021, 19:30

Invited Oral

The National High Magnetic Field Laboratory headquartered at Florida State University in Tallahassee, Florida, USA designs, builds, and operates a variety of ultra-high field magnets including superconducting magnets providing up to 32 T, dc resistive magnets providing up to 41.5 T, resistive/superconducting hybrid magnets up to 45.1 T, and pulsed magnets up to 100 T. Some of the "lessons...

1068. [Invited] Lessons Learned in No-insulation HTS Magnet Technology (WED-SS-05)

Seungyong Hahn (Seoul National University)

17/11/2021, 19:50

Invited Oral

Firstly reported by MIT in 2010, the no-insulation (NI) high temperature superconductor (HTS) winding technique introduced a new philosophy of HTS magnet protection: “current sharing” with adjacent turns upon a quench. The protection mechanism of the NI HTS technique was later explained by RIKEN: the multi-turn-to-single-turn transition. To mitigate the charging delay, a major drawback of NI...

1064. [Invited] Bringing a Nuclear Quality Approach to Superconducting Magnets (WED-SS-06)

Liao Min (ITER organization)

17/11/2021, 20:10

Invited Oral

Quality Assurance (and the derived quality controls) define the Nuclear Quality Approach in ITER. The higher the impact of manufacturing and assembly errors, then the more rigorous the QA regime, leading eventually to Safety Specific controls such as the appointment of an Authorised Notified Body ANB, by the Safety Regulator. Requirements come from regulatory and safety surveillance, quality...
